out of curiosity, can you take a Verizon iPhone 4S, unlock it, and then activate it on At&t? T-mobile?
I understand why you can't go from at&t version to verizon because there is no CDMA component to the phone. Just wondering if the opposite would work.

No.

While the iPhone4S physically has the capabilities - they are all quad band radio equipped - phones made by Apple for Verizon or AT&T are "locked" deep within the OS/radio firmware so they can not be made to be interchangeable.
